Understanding the HW-416-B PIR Sensor: A Comprehensive Guide
- Sensitivity (Range): This adjusts how far away the sensor "sees." Turn it clockwise to increase the range (up to 7m) or counter-clockwise to decrease it (down to ~3m). This is perfect if you want to avoid detecting motion from the street outside your window.
- Time Delay: This determines how long the sensor stays "HIGH" (active) after it detects motion.
2. Key Features
- Operating Voltage: 4.5V – 20V DC (5V – 12V recommended)
- Static Current: < 50 µA (ultra-low power consumption)
- Output Signal: 3.3V TTL logic (HIGH when motion detected, LOW when idle)
- Delay Time (Tx): 0.3 sec – 600 sec (adjustable via potentiometer)
- Block Time (Tb): 2.5 sec (fixed; sensor ignores new triggers during this period)
- Trigger Modes: Single trigger (non-repeatable) / Repeatable trigger (jumper selectable)
- Detection Range: Up to 7 meters (adjustable)
- Detection Angle: < 110° cone (lens dependent)
- Operating Temperature: -15°C to +70°C
- PCB Dimensions: 32 mm × 24 mm × 28 mm (with lens)
The "Logic Level" Advantage
One of the most convenient features of the HW-416-B for microcontroller users is its logic interface. It operates on a simple High/Low digital logic: hw-416-b pir sensor datasheet
